Support Logs erstellen

A) For standalone switch:

-issue the command #run request support information | save /var/tmp/RSI.txt

-issue the command #run file archive compress source /var/log/ destination /var/tmp/VARLOG

-do ftp or http to the switch in order to download the RSI.txt and the VARLOG files from the /var/tmp

directory then attach them to the case

B) For virtual-chassis:

-issue the command #run request support information all-members | save /var/tmp/RSI-All-Members.txt

-follow this KB in order to collect logs: https://kb.juniper.net/InfoCenter/index?page=content&id=KB15186

-do ftp or http to the switch in order to download the RSI-All-Members.txt and the VARLOG files from the /var/tmp directory then attach them to the case‘

Root Shell erlangen und Dateien runterladen

Follow the steps below to collect all the files from the /var/log directory of each member of a virtual chassis.

NOTE: You will need FTP, SSH, HTTP (JWEB) or USB access to the EX Switch to copy the logs from the Switch.

1. Login to the EX Virtual Chassis (VC) using the management IP address or console. You will be logged into the primary switch of the EX Virtual Chassis. In this example, member 0 is the primary switch. {master:0} user@router>
2. Login to the shell prompt as the root user. user@router> start shell user root
3. Use the „tar“ command to compress the folder /var/log and its contents.  The file will be saved to /var/tmp directory root% tar -zcvf /var/tmp/varlog-mem0.tar.gz /var/log/*
4. Verify whether the tar.gz file has been created root% ls /var/tmp
.ssh varlog-mem0.tar.gz
5. Exit from the shell prompt using the command „exit“ and you will be placed on the CLI prompt of Primary switch {master:0}
root% exit
6. Request a session to the next member of the virtual chassis using its member ID.  To verify which member you are connected to, use the „show virtual chassis“ command and it will display an asterisk * next to the member you are connected to. root> request session member 1
7. Login to the shell as the root user root> start shell user root
8. Use the „tar“ command to compress the folder /var/log and its contents. root% tar -zcvf /var/tmp/varlog-mem1.tar.gz /var/log/*
9. Verify whether the tar.gz file has been created root% ls /var/tmp
.ssh varlog-mem1.tar.gz
10. Go to the CLI of current member to copy the member log files to primary. root% cli
11. Execute the file copy command to copy the tar.gz file from the current member switch to the /var/tmp directory on primary switch root> file copy fpc1:/var/tmp/varlog-mem1.tar.gz fpc0:/var/tmp/
12. Exit from the current member session. Now you will be logged back into the Primary switch. root> exit
13. Repeat steps 6 through 12 by changing the member id until all the member logs are loaded to the primary switch. Be sure to name each file according the member id to easily identify.

Now the files can be directly copied from the EX Virtual Chassis primary to any local host using ftp, scp, JWEB, or mounted USB.

NOTE: FTP, SSH and HTTP are configured under the ’system services‘ stanza.  See Related Links below.
